In some embodiments, the positioning hole 111 may be provided on the top wall of the first housing 11. In some embodiments, a limiting opening 112 may be provided at one end of the first housing 11, and the limiting opening 112 may be used to limit the second wire passing unit 20 in a retracted state. In some embodiments, a first wire passing channel 441 may be provided in the first housing 11, and the first wire passing channel 441 may be formed on the driving mechanism 40 in the first housing 11. A limiting structure for limiting the transmission rack 30 is provided in the inner side wall of the first housing 11, that is, the inner side wall of the first housing 11a and the second housing 11b. The limiting structure can limit the maximum distance that the transmission rack 30 can extend. In some embodiments, the limiting structure can be a limiting clip. The limiting clip can be in the shape of a long strip, which can limit the direction in which the transmission rack 30 moves.

[0050] Further, in some embodiments, the second wire passing unit 20 can be clamped in the limit opening 112 when it is retracted. The second wire passing unit 20 can include a second housing 21, the second housing 21 can be arranged in a longitudinal direction, and the second housing 21 can form a set angle with the first housing 11.

In some embodiments, a control circuit board connected to the wire 100 can also be arranged in the second housing 21. Further, in some embodiments, the second wire passing unit 20 can include a clamping structure 22, and the clamping structure 22 can be used to clamp with the transmission rack 30. In some embodiments, the engaging structure 22 may include a slot, and one end of the transmission rack 30 may be engaged in the slot.

[0051] like Figure 6 and Figure 7As shown, further, in some embodiments, one end of the transmission rack 30 can be connected to the second housing 21, and the other end can be inserted into the first housing 11. The transmission rack 30 can be arranged along the length direction of the first housing 22. The transmission rack 30 can drive the second housing to telescopic movement through reciprocating motion in the unlocked state. In some embodiments, the transmission rack 30 may include a body 31, a transmission tooth portion 32, and a through slot 33. The body 31 can be arranged longitudinally, and the body 31 may include a top wall, and two oppositely arranged side walls arranged on two opposite sides of the top wall and extending downward. The transmission tooth portion 32 can be arranged on the body 31. Specifically, in some embodiments, the transmission tooth portion 32 can be arranged on the top wall of the body 31. The through slot 33 can be arranged on the body 31 and arranged along the length direction of the body 31, and can be used for the installation of the driving mechanism 40. In some embodiments, the through slot 33 can be arranged between two oppositely arranged side walls of the body 31, and both ends are through. In some embodiments, a positioning sleeve 34 may be provided in the through slot 33 , and the positioning sleeve 34 may be used to position and install the driving mechanism 40 .

[0052] Further, in some embodiments, the driving mechanism 40 may include a first guide cylinder 41, a second guide cylinder 42, a first elastic member 43, and a second elastic member 44. The first guide cylinder 41 may be arranged along the length direction of the transmission rack 30, the second guide cylinder 42 may be arranged to extend and extend from the first guide cylinder 41, the first elastic member 43 may be sleeved on the first guide cylinder 41, and may drive the transmission rack 30 to reciprocate. The second elastic member 44 may be arranged in the second guide cylinder 42, and may apply a pulling force to the second wire passing unit 20.

[0053] Specifically, the first guide cylinder 41 can be inserted into the through slot 33 and passed through the positioning sleeve 34, and one end is fixed to the side wall of the end of the first housing 11, and the other end is extended along the length direction of the through slot 33. The first guide cylinder 41 can be a hollow structure with two ends passing through. In some embodiments, a washer 45 can be provided on the first guide cylinder 41, and the washer 45 can be sleeved on the periphery of the first guide cylinder 41, and can be provided near the end of the first guide cylinder 41 connected to the first wire passing unit 10, and can cooperate with the first elastic member 43.

[0054] The outer diameter of the second guide cylinder 42 may be smaller than the inner diameter of the first guide cylinder 41, and one end of the second guide cylinder 42 may be connected to the end of the transmission rack 30 disposed near the second wire passing unit 20, thereby driving the transmission rack 30 to move telescopically, and further driving the first housing 11 to move telescopically. The second guide cylinder 42 may be a hollow structure with two ends penetrated.

[0055] When the transmission rack 30 is in a locked state, one end of the first elastic member 43 can abut against the washer 45, and the other end can abut against the positioning sleeve 34, and the first elastic member 43 is in a compressed state. The pressure applied by the first elastic member 43 to the transmission rack 30 is greater than the reaction force of the second line-passing unit 20 (that is, greater than the friction between the first housing 11 and the transmission rack 30, the friction between the first guide cylinder 41 and the second guide cylinder 42, the friction between the second guide cylinder 42 and the transmission rack 30, and the pulling force of the second elastic member 44). When the transmission rack 30 is in an unlocked state, the first elastic member 43 is in a telescopic state, which can drive the transmission rack 30 to pop out, and then drive the second line-passing unit 20 to stretch away from the first line-passing unit 10. In some embodiments, the first elastic member 43 can be a compression spring. It can be understood that in some other embodiments, the first elastic member 43 may not be limited to a compression spring.

[0056] The second elastic member 44 may be arranged in the second guide cylinder 42, one end of which may be connected to one end of the first wire passing unit 10 away from the second wire passing unit 20, and the other end may be connected to the second wire passing unit 20. When the second wire passing unit 20 is extended, the second elastic member 44 may apply a pulling force to the second wire passing unit 20. The second elastic member 44 may be columnar, and may be a hollow structure with two ends passing through. The inner side of the second elastic member 44 may form a first wire passing channel 441. In some embodiments, the second elastic member 44 may be a torsion spring, and the central channel of the torsion spring may form the first wire passing channel 441.

[0057] Further, in some embodiments, the lock assembly 50 may be disposed in the first housing 11, and may be used to lock or release the transmission rack 30. In some embodiments, the lock assembly 50 may include a lock 51, a rotating shaft 52, and an elastic body 53. The lock 51 may be locked with the transmission rack 30. The rotating shaft 52 may be disposed on the lock 51, and both ends may pass through the lock 51, and may be rotatably connected to the first wire passing unit 10, specifically, may be rotatably connected to the first housing 11a and the second housing 10b. In some embodiments, the elastic body 53 may be sleeved on the rotating shaft 52, and may be used to apply a torsional force to the rotating shaft 52.

[0058] Further, in some embodiments, the lock buckle 51 can be arranged on the transmission tooth portion 32 of the transmission rack 30, and the lock buckle 51 includes a matching portion 511 and a locking portion 512. The matching portion 511 can be used to connect with the trigger button 60, and the trigger button 60 can drive the locking portion 512 to lock or release the transmission tooth portion 32 of the transmission rack 30 by triggering the matching portion 511. The locking portion 512 can be arranged at one end of the matching portion 511, and its length can be greater than the length of the matching portion 511, and can be integrally formed with the matching portion 511. The locking portion 512 can include a main body 5121 and two locking hooks 5122. The main body 5121 can be arranged on the transmission tooth portion 32, and the two locking hooks 5122 can be arranged on the bottom surface of the main body 5121, and can be arranged near the end of the main body 5121 away from the matching portion 511. The two locking hooks 5122 can be spaced apart and arranged side by side and protrude from the bottom surface of the main body 5121 . The space between the two locking hooks 5122 can form a buckle groove 5123 , and the buckle groove 5123 can be locked with the transmission rack 30 . In some embodiments, the buckle groove 5123 can be locked with the transmission tooth portion 32 .

[0059] In some embodiments, the rotating shaft 52 may be disposed between the matching portion 511 and the locking portion 512. When the matching portion 511 is pressed down, the rotating shaft 52 may be driven to rotate, and under the action of the elastic body 53, the locking portion 512 may be tilted upward to release the transmission rack 30. When the trigger button 60 is reset, the matching portion 511 rises, which may drive the rotating shaft 52 to rotate, and under the action of the elastic body 53, the locking portion 512 falls back and engages with the transmission rack 30.

[0060] In some embodiments, the elastic body 53 can be a torsion spring, which can be sleeved on the rotating shaft 52, and the pressure foot at one end can elastically abut against the first shell 11, and the pressure foot at the other end can abut against the locking portion 512, thereby applying a torsional force to the rotating shaft 52.

[0061] Further, in some embodiments, the trigger button 60 may be disposed on the first housing 11 and located in the positioning hole 111. In some embodiments, the trigger button 60 may include a button body 61 and a trigger portion 62. The button body 61 may be cylindrical and may be disposed on the first line passing unit 10, specifically, may be located in the positioning hole 111. The trigger portion 62 may be disposed on the button body 61 and may be inserted into the first line passing unit 10 to be connected with the matching portion 511. The trigger portion 62 may be in the shape of an elongated cylinder, and its radial dimension may be smaller than the radial dimension of the mounting body 61. One end of the trigger portion 62 may be against the matching portion 511.

[0062] When the wire passing device is in use, when the driving mechanism 40 is in the closed state, Figure 4After pressing the trigger button 60, the locking portion 512 of the lock buckle 51 is tilted, and the two locking hooks 5122 of the locking portion 512 are disengaged from the transmission tooth portion 32 of the transmission rack 30. At this time, the first elastic member 43 can apply pressure to the transmission rack 30, and the pressure can be greater than all the forces acting on the transmission rack 30 and the second line-passing unit 20, so that the transmission rack 30 is ejected, and then the second line-passing unit 20 is extended. When the transmission rack 30 moves to the farthest distance (when the movement is limited by the limit structure), a balanced state is formed. Figure 5 When the trigger button 60 is released, the trigger button 60 is reset and a thrust can be applied to the second line-passing unit 20. At this time, the transmission rack 30 can be locked by the two lock hooks 5122 of the locking portion 512. As the second line-passing unit 20 is continuously pushed into the limit opening 112 of the first housing 11, the transmission rack 30 is also pressed by the two lock hooks 5122 in an amplitude manner (i.e., the transmission rack 30 removes the thrust for each periodic distance of one tooth of the transmission rack 30). The transmission rack 30 can be locked by the lock buckle 51, and the entire device is in a balanced state, and the second line-passing unit 20 also moves stationary. Due to the interaction between the transmission rack 30 and the lock buckle 51, the second line-passing unit 20 is in a stationary state even if it is pulled backward.

[0063] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
